Description

Technical Field

[0001] This utility model belongs to the field of hot melt adhesives, specifically relating to a water-cooled production line for film-coated hot melt adhesives. Background Technology

[0002] In the production process of film-coated hot melt adhesive, the hot melt adhesive needs to be rapidly cooled and shaped after being extruded from the extruder to ensure its physical properties and appearance quality.

[0003] After being cut into blocks or strips, the film-coated hot melt adhesive is cooled and shaped. Traditional water-cooling line equipment usually uses simple cooling water tanks or spray cooling methods, which do not have sufficient precision in water temperature control. This can cause the water temperature to be too low, which can easily lead to surface defects or uneven internal stress in the film-coated hot melt adhesive during cooling. This can cause the film on the hot melt adhesive surface to fall off or crack, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a water-cooled production line for film-coated hot melt adhesives, thereby solving the problems mentioned in the background section. To achieve the above objective, this invention provides the following technical solution: including a water tank and a cooling device installed on the water tank;

[0005] The cooling device includes several shells arranged in a stepped manner. A feed inlet is fixedly provided on the upper side of one side of each shell, and a discharge outlet is fixedly provided on the other side of each shell. The feed inlets and discharge outlets on two adjacent shells abut against each other. The shells are also provided with a conveying mechanism and a temperature control mechanism.

[0006] It should be noted in the solution that the conveying mechanism includes a rotating rod rotatably disposed between the two side walls of the housing and a number of push plates equidistantly distributed on the rotating rod. An arc-shaped baffle is also fixedly disposed between the two side walls of the housing, and the arc-shaped baffle is located below the push plates.

[0007] It should be noted in the solution that the temperature control mechanism includes a heater and a sensor installed on the inner wall of the housing.

[0008] It should be noted in the solution that a water pump is installed on the outer wall of the water tank, and an outlet pipe is fixed to the output end of the water pump. The end of the outlet pipe passes through the housing. An inlet pipe is fixed to the input end of the water pump, and the end of the inlet pipe passes through the water tank.

[0009] It should be noted in the solution that both the push plate and the arc-shaped baffle have several mesh holes on their surfaces.

[0010] Compared with the prior art, the water-cooled production line for film-coated hot melt adhesive provided by this utility model has at least the following beneficial effects:

[0011] (1) By setting up a cooling device, in actual use, hot melt adhesive enters the first housing through the feed port and then enters the next housing through the conveying mechanism inside the housing. The temperature of the coolant in each housing can be controlled by the temperature control mechanism. The conveying mechanism can be controlled to control the transport speed of the hot melt adhesive, and the temperature control mechanism can be controlled to control the temperature inside each housing. This can effectively prevent the hot melt adhesive from deforming and ensure the quality of the hot melt adhesive.

[0012] (2) With the setting of the conveying mechanism, in actual use, the hot melt adhesive enters the shell through the feed port. At this time, the hot melt adhesive is located above the arc baffle and is blocked by a push plate on one side. Start the rotating rod so that the push plate rotates with the rotating rod. The rotation of the push plate will push the hot melt adhesive above the arc baffle until the hot melt adhesive on the arc baffle is pushed to the discharge port. When the push plate that pushes the hot melt adhesive reaches the side of the discharge port, the hot melt adhesive enters the discharge port. At this time, there are two situations. The first situation is that the hot melt adhesive is not completely cooled and enters the next shell from the discharge port to continue cooling. The second situation is that after cooling through several shells, the hot melt adhesive has been completely cooled and formed. At this time, the hot melt adhesive enters the next production process through the discharge port. The conveying mechanism can effectively transport the hot melt adhesive from the shell to the next shell. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4A water-cooled production line for film-coated hot melt adhesive includes a water tank 1 and a cooling device installed on the water tank 1. The cooling device includes several shells 2 arranged in a stepped manner. An inlet 7 is fixedly installed on the upper side of one side of the shell 2, and an outlet 8 is fixedly installed on the other side of the shell 2. The inlet 7 and outlet 8 on two adjacent shells 2 abut against each other. The shell 2 is also provided with a conveying mechanism and a temperature control mechanism.

[0020] With the cooling device in place, in actual use, the hot melt adhesive enters the first housing 2 through the inlet 7, and then enters the next housing 2 through the conveying mechanism inside the housing 2. The temperature of the coolant in each housing 2 can be controlled by the temperature control mechanism. For example, the temperature of the coolant in the first housing 2 is (40-50℃), which reduces the initial temperature of the hot melt adhesive; the temperature of the coolant in the second housing 2 is (20-30℃), which further cools it; and the temperature of the coolant in the final cooling housing 2 is (10-15℃), which completes the cooling of the main body. The conveying mechanism can be controlled to control the transport speed of the hot melt adhesive, and the temperature control mechanism can be controlled to control the temperature in each housing 2. This can effectively prevent the hot melt adhesive from deforming and ensure the quality of the hot melt adhesive.

[0021] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the conveying mechanism includes a rotating rod rotatably disposed between the two side walls of the housing 2 and several push plates 6 equidistantly distributed on the rotating rod. An arc-shaped baffle 10 is also fixedly disposed between the two side walls of the housing 2. The arc-shaped baffle 10 is located below the push plates 6. A motor 5 is installed on the outer wall of the housing 2. The output shaft of the motor 5 rotatably passes into the housing 2 and is fixedly connected to the rotating rod.

[0022] With the conveying mechanism in place, hot melt adhesive enters the housing 2 through the inlet 7 during actual use. At this time, the hot melt adhesive is located above the arc-shaped baffle 10 and is blocked by a push plate 6 on one side. The motor 5 is started, causing the push plate 6 to rotate with the rotating rod. The rotation of the push plate 6 pushes the hot melt adhesive above the arc-shaped baffle 10 until it pushes the hot melt adhesive on the arc-shaped baffle 10 to the outlet 8. When the push plate 6 pushing the hot melt adhesive reaches the side of the outlet 8, the hot melt adhesive enters the outlet 8. At this time, there are two situations: first, the hot melt adhesive is not completely cooled and enters the next housing 2 from the outlet 8 to continue cooling; second, after cooling in several housings 2, the hot melt adhesive has completely cooled and formed. At this time, the hot melt adhesive enters the next production process through the outlet 8. The conveying mechanism can effectively transport the hot melt adhesive from the housing 2 to the next housing 2.

[0023] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the temperature control mechanism includes a heater 11 and a sensor 12 installed on the inner wall of the housing 2, and both the heater 11 and the sensor 12 are connected to a control board;

[0024] With the temperature control mechanism in place, the temperature inside the housing 2 can be detected by the sensor 12 during actual use. Based on the required temperature inside the housing 2, the water tank 1 can be controlled to heat or cool the coolant inside the housing 2, so that the coolant inside each housing 2 is within a suitable range. This can effectively control the temperature of the coolant and improve cooling efficiency.

[0025] Furthermore, referring to Figure 1-4 As shown, it is worth noting that a water pump 4 is installed on the outer wall of the water tank 1. The output end of the water pump 4 is fixed with a water outlet pipe 3, and the end of the water outlet pipe 3 is inserted into the housing 2. The input end of the water pump 4 is fixed with a water inlet pipe 9, and the end of the water inlet pipe 9 is inserted into the water tank 1.

[0026] With the water pump 4 installed, the coolant in the housing 2 will be lost during actual use. The coolant in the water tank 1 needs to be transported to the housing 2 by the water pump 4, which can effectively replenish the coolant. When the coolant temperature in the housing 2 is too high, it can also be cooled down by adding coolant, which can save energy.

[0027] Furthermore, referring to Figure 1-4 As shown, it is worth noting that both the push plate 6 and the arc-shaped baffle 10 have a number of mesh holes on their surfaces.

[0028] With the mesh design, in actual use, the hot melt adhesive is on the arc-shaped baffle 10, and the pusher plate 6 pushes the hot melt adhesive. The coolant is inside the housing 2. By opening the mesh in the pusher plate 6 and the arc-shaped baffle 10, the coolant will not move out of the housing 2 when the pusher plate 6 rotates, thus reducing the waste of coolant.

[0029] The above describes a water-cooled production line for film-coated hot melt adhesive provided by this utility model. Specific preferred embodiments have been used to illustrate the principles and implementation methods of this utility model. These embodiments are only for the purpose of helping to understand the principles and core ideas of this utility model. It should be noted that for those skilled in the art, the implementation schemes in the above embodiments can be further combined or replaced without departing from the design concept of this utility model, and several improvements and modifications can be made to this utility model. These improvements and modifications also fall within the protection scope of the claims of this utility model.
